Question

What are the domain and range of the function y = -5*?

OA) Domain: all real numbers
Range: negative real numbers
OB) Domain: all real numbers
Range: positive real numbers
OC) Domain: negative real numbers
Range: all real numbers
OD) Domain: positive real numbers
Range: all real numbers

Answer 1

correct answer is:

OA) Domain: all real numbers
Range: negative real numbers

Step-by-step explanation:

The function y = -5x is a linear function with a constant slope of -5. The domain of the function is all real numbers, because there are no restrictions on the input values of x.

The range of the function, however, is limited. Since the coefficient of x is negative, the function will always yield negative values. Therefore, the range is negative real numbers.

So, the correct answer is:

OA) Domain: all real numbers
Range: negative real numbers
